To all whom it ma concern:

Be it known that I, THEODORE C. MENGES, a citizen of the United States of America, and a resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Bolster-Supports for Cylinders of Internal-Combustion Engines, of which the following is a specification.

My invention relates to supports for cylinders of internal-combustion engines, and the object of my improvement is to furnish means for propping an overhanging cylinder as used on engines of this type, to preserve same from sagging and hold it rigidly in [position relative to the engi e ase.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of an internal-combustion. engine with bracketed cylinder, and having my improved pedestal or support for said cylinder. 1

Fig. 2 is an enlarged detail elevation of the said pedestal, with parts thereof broken away, and vertically sectioned.

Fig. 8 is a similar view of a pedestal having an adjusting-device comprised therewith.

Fig. 4 is another similar view of a pedestal supplied with a wedge adjusting-means therefor.

Fig. 5 is an other similar view of a pedestal having an adjustable threaded connection to said cylinder.

Similar numerals of reference denote corresponding parts throughout the several views.

As many internal-combustion engines for convenience have their cylinders mounted on the engine-base in an overhanging or bracketed manner, I have provided means for supporting the overhanging cylinder so as to secure it in a firm position, and pr vent it from working loose.

The engine shown in Fig. 1 is of this type, wherein the cylinder 1 overhangs the base 8 being bolted or secured by screws to the crank-case which latter is mounted on said base. The cylinder is provided with a depending boss 2 spaced from the underlying end of the base 8. A pedestal 4 in the at IEGl-Bfit at a flanged coupling, has its upper annular flange secured to the boss 2 1 by meansof the screws 5, while the lower flange 7 is secured to the base 8 by means of screws 6. Since the pedestal .4: is. placed medially lengthwise of the cylinder, it supports the overhanging weight of the cylinder. This form j of pedestal is both simple, inexpensive and readily fitted. However, in the event that some adjustment: should be required between the partsin order] to do away with the necessity jof extra machinework, or to take up for shrinkage in castings, or.for"other reasons, I have provided thepedestals shownin Figs. 3 to 5 inclusive, in which provision is made for that purpose, in slightly variant ways.

In Fig. 3 the base 8, also the boss 2 have integral opposed and similar frustums 9 and 10 respectively, which are adapted to fit similarly formed. seats in the upper and lower ends of the pedestal 4-. It isnot necessary to employ special fastening-means for the parts, since the weight of the cylinder tends to cause them to fit closely together, but since there might be in some cases where the unm'achined castings are used some looseness between the parts, I have made central vertical threaded sockets in the said frustums to receive the threaded alined rods 11 and 14: respectively, said rods being connected by means of a turn-buckle 13. By turning the turnbuckle the bosses may be drawn toward each other to insure a tightfit with the coned seats in the pedestal with out danger of shifting, and thus holding the cylinder tightly and securely against vertical or transverse displacements. A hand-hole 12 is provided in the pedestal 4: in order to render it possible to manipulate the turnbuckle 13. I

In Fig. 4 is shown an alternative device, wherein the top of the pedestal 4: is made solid at 21 with its upper surface slightly oblique so that a wedge 16 may be adjustably seated between said surface and the under horizontal surface of the boss 2. In this case slots 20 and 15 are provided in the wedge in alinement to receive the fastening screws 5, yet permitting adjustment of the wedge along the boss and pedestal top. A

lug 18 is integral with the cylinder and horiand secured to striding lav a nut 19. By this tie means the parts may be fitted adjustably as necessary.

In Fig. 5 isshown a variant means for adjusting said parts, wherein a block 23 is secured to the boss 2 by screws 5 said block having a depending interiorly-threaded integral ring 22 adapted to receive the exteriorly-threaded upper end of the pedestal 4; at 24, the pedestal in this case having the upper flange omitted. The pedestal is adjusted within the ring 22 before being secured to the base 8 by means of the screws 6.

In all these slightly variant supportingmcans for the cylinder, the strains arising from the weight of the cylinder and its 0011+ tained moving mechanism is taken away from its connection to the frame, which prevents breakage at that location. I g The ordinary castings may be used, without considerable outlay in machining same. 1 Having described my invention, what I claim as new-, and' desire to secure by Letters Patent, is: i

0 1. The combination with an engine base,

of a cylinder detachably connected thereto in an overhanging position, said cylinder having a frustal boss, a hollow pedestal having a coned seat at an end of its hollow to receive said boss, and means connected to said boss operable to draw the boss into fitting contact with said coned seat.

2. The combination with an engine base having a raised part, of a cylinder detachably bracketed on an end of said raised part to overhang the base, both the cvlinder and the base having vertical alined spaced frustal bosses, and a pedestal alined between said bosses, and having hollow coned seats in its ends to receive said bosses and fit same to hold the cylinder in a certain position with relation to the base.

THEODORE C. MENGE'S.
